我正在逆时针处理日食中的窗口。当我运行此代码时：

(require 'http-kit)
;; start concurrent requests, get promise, half the waiting time

    (let [response1 (http-kit/get "https://clojure.org")
          response2 (http-kit/get "http://clojure.org/")]
      ;; Handle responses one-by-one, blocking as necessary
      ;; Other keys :headers :body :error :opts
      (println "response1's body: " (:body @response1))
      (println "response2's status: " (:status @response2)))

我收到以下消息：

CompilerException java.io.FileNotFoundException：无法在类路径上找到 http_kit__init.class 或 http_kit.clj。请检查带有破折号的命名空间是否在 Clojure 文件名中使用下划线。，编译:(restful_clojure\test.clj:1:1)

所以，接下来我运行：



    (println (seq (.getURLs (java.lang.ClassLoader/getSystemClassLoader))))

之后我得到：

(#object[java.net.URL 0x50b65482 文件:/E:/workspace/restful-clojure/test/] #object[java.net.URL 0x5f5d7651 文件:/E:/workspace/restful-clojure/src/] #对象[java.net.URL 0x2878624e 文件：/E:/workspace/restful-clojure/dev-resources] #object[java.net.URL 0xe56e16d 文件：/E:/workspace/restful-clojure/resources/] #object [java.net.URL 0x6c26a661 文件：/E:/workspace/restful-clojure/target/classes/] #object[java.net.URL 0x58fdaa4a 文件：/C:/Users/Maciek/.m2/repository/clojure-完成/clojure-complete/0.2.3/clojure-complete-0.2.3.jar] #object[java.net.URL 0x337cc909 文件：/C:/Users/Maciek/.m2/repository/http-kit/http- kit/2.1.19/http-kit-2.1.19.jar] #object[java.net.URL 0xa181b82 file:/C:/Users/Maciek/.m2/repository/org/clojure/clojure/1.8.0/ clojure-1.8.0.jar] #object[java.net.URL 0x53d4a10e 文件：/C:/Users/Maciek/.m2/repository/ccw/ccw.server/0.2.0/ccw.server-0。2.0.jar] #object[java.net.URL 0x664eeec4 文件:/C:/Users/Maciek/.m2/repository/org/clojure/tools.nrepl/0.2.10/tools.nrepl-0.2.10.jar] #object[java.net.URL 0x33af4785

如您所见，http-kit 已加载

#object[java.net.URL 0x337cc909 文件：/C:/Users/Maciek/.m2/repository/http-kit/http-kit/2.1.19/http-kit-2.1.19.jar]

奇怪的是，它在上次系统重新启动之前运行良好。

这是我的 project.clj


    ;(defproject restful-clojure "0.1.0-SNAPSHOT"
    ;  :description "FIXME: write description"
    ;  :url "http://example.com/FIXME"
    ;  :license {:name "Eclipse Public License"
    ;            :url "http://www.eclipse.org/legal/epl-v10.html"}
    ;  :dependencies [[org.clojure/clojure "1.6.0"]])
    ; project.clj
    (defproject restful-clojure "0.1.0-SNAPSHOT"
      ; ...project settings...

      ; The :dependencies key maps to a vector containing all dependencies
      ; necessary for our project. The dependency on Clojure itself should
      ; have already been added by Leiningen. We will add Ring, the Jetty
      ; adapter (so we can start up a web server to serve our application),
      ; and Compojure, which we will use later on in this tutorial.
      :dependencies [[org.clojure/clojure "1.8.0"]
                     [http-kit "2.1.19"]])

这不完全是问题的答案，但它是相关的，我在尝试解决我的错误时发现了这个问题，所以我认为这可能对其他人有所帮助。

我得到了与 OP 相同的错误，因为我忘了添加

[http-kit "2.2.0"]

:dependencies []在 project.clj里面。

OP 的依赖行是正确的，但在调用(require). OP 问题的实际答案在评论中，到目前为止还没有变成答案。
